Swift 5 Building Logic & Unit Tests in Playground Episode 4 Part 2
Building game logic using unit tests with Swift 5 in Xcode Playground - with an example of refactoring.
This is Part 2 of 2 videos where I implement a feature of the game logic. I will complete all the user stories for the first feature and show how I refactored my code.
Red - Make it fail
Green - Make it work
Refactor - Make it better
I’ve recently been trying my hand at writing unit tests and practicing Test-Driven Development (TDD) using Swift 5. It’s quite easy to write them in an existing app, but I want to separate and try to test functionality outside of one. The hope is to do validation without the distraction. Once I’m done with the Playground tests, I can move the working code and its tests back into the app.
Coding in isolation can help keep functionality isolated, avoid tightly coupling code, and other jargon phrases from interfering with what I’ve already built in the app.
